OHMS law

What size resistor would produce a 3 Amp current flow with a 12 Volt battery

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V
• 10 V
• 2.5 V
• 0.4 V

Current times Resistance equals
 (I X R)

• Power
• Voltage
• Amperage
• Ohm

If the Voltage stays the same and Resistance is increased, Current will 

• Increase
• Decrease
• Stay the same
• X
